Part 1: What is File Transfer Protocol ? File Transfer Protocol is a set of standard protocols used for file transfer over the network, which works at the seventh layer of the OSI model and the fourth layer of the TCP model, i.e., the application layer. This ensures that the connection between the client and the server is reliable and connection-oriented, providing a reliable guarantee of data transmission. Part 2: How does File Transfer Protocol Work? File Transfer Protocol uses the user interface of the Internet's standard file transfer protocol, FTP, to provide users with a set of applications for managing file transfers between computers. FTP is designed based on the client-server model, where two communications channels are established between the client and the FTP server. Command Channel cannot perform the task of transferring data and can only be used to transfer control information such as internal commands executed by FTP and the responses to the commands; Data 12Channel is a connection for transferring files between the server and the client, which is full-duplex and allows simultaneous data transfer in both directions. This idea of separate transmission of commands and data greatly increases the efficiency of FTP, while other client server applications typically have only one TCP connection. Th121 client initiates a conversation with the server when the user requests the server to download a file. Using FTP, the client can upload, download, delete, move, and rename files on the server. Part 3: Two Modes of FTP FTP client initiates FTP session and establishes corresponding connection with FTP server. Two channels are to be established during FTP session: control information process and data process. Standard : Standard mode FTP client sends PORT command to FTP server. Passive : Passive mode FTP client sends PASV command to FTP Server. Part 4: FTP Transfer Method The task of the FTP is to transfer files from one computer to another, independent of the location of the two computers, the way they are connected, or even whether they use the same operating system. There are two ways to transfer FTP: ASCII, Binary. ASCII Assuming that the file the user is copying contains simple ASCII text, if the remote machine is not running UNIX, when the file is transferred ftp will usually automatically adjust the contents of the file to facilitate the interpretation of the file into the format in which the text file is stored on the other computer. Note: It is often the case that the file the user is transferring contains files that are not text files; they may be programs, databases, word processing files, or compressed files. Before copying any non-text files, use the binary command to tell ftp to copy them. Binary In a binary transfer, the bit sequence of the file is preserved so that the original and the copy are bit-by-bit one-to-one. Even if the file containing the bit sequence on the destination machine is meaningless. Note: If a binary file is transferred in ASCII, it will still be translated even if it is not needed. This can corrupt the data. Part 5: User classification of FTP Real Account This type of user is the one who has an account on the FTP service. When this type of user logs in to the FTP server, their default home directory is the directory named by their account. However, they can also change to other directories. For example, the home directory of the system, etc. Guest User In FTP server, we often set up an account for different departments or a specific user. However, this account has the feature that it can only access its own home directory. In this way, the server secures other files on the FTP service. An account with this type of user can only access the directories under its home directory, but not files outside its home directory. Anonymous User This is also what we usually call anonymous access. This type of user is not assigned an account in the FTP server, but he/she can still access some public resources anonymously. Part 6: The Development of FTP FTP is the oldest network tool in the development of the Internet. From 1971, when the first RFC for FTP was proposed by A KBHUSHAN to nearly half a century ago, FTP has been one of the most important and widely used services in the Internet with its unique advantages. With the continuous development of the Internet, the FTP specification has undergone several revisions to accommodate network standards including TCP/IP. In 1980, jon postel, a scientist at the Institute of Information Science at the University of Southern California, defined a new version of FTP in RFC 765. In 1985, RFC 959 redefined FTP, this time introducing new administrative features, including the ability to create and delete file directories. In 1997, REC 959 was updated to provide new features defined in RFC 2228 to provide security features. In 1999, FTP was updated to RFC 2428 to support the IPv6 protocol. Part 7: 7 Common File Transfer Protocols FTP FTP is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol connections. Within the TCP/IP suite, FTP is considered an application layer protocol. FTPS FTPS a multi-transfer protocol, equivalent to an encrypted version of FTP. When sending and receiving files on the FTP server, you face two risks. The first risk is to encrypt the files when uploading files. The second risk is that these files will stay on the FTP server while waiting for the recipient to download them, at which point they need to be secured. Measure: Choose to create an FTP server that supports SSL, i.e., use an encrypted control and data channel with an SSL layer under the FTP protocol to allow the host to upload these files using an FTPS connection. TLS & SSL TLS is an industry standard designed to protect the privacy of information during network communications, allowing client and server applications to detect security risks including message tampering, message interception, message forgery, and its predecessor, SSL. TLS and SSL encrypt network connections at the transport layer, but work below the application layer. SSL security extensions have at least two different initialization methods: explicit security and implicit security. SSH(Secure Shell） SSH is a security protocol based on the application layer. SSH is currently a more reliable protocol that provides security for remote login sessions and other network services, and the use of SSH protocol can effectively prevent the leakage of information during remote management. SCP The SCP protocol is an application layer protocol that defines the process of transferring files "between local and remote machines" or "between remote and remote machines". The SCP protocol is based on the SSH protocol, so file transfers based on the SCP protocol are secure. SFTP SFTP is a secure file transfer protocol that provides a secure encryption method for transferring files. It has almost the same syntax and functions as FTP, but SFTP is part of SSH, a secure way to transfer files to a server. SFTP also uses encryption to transmit authentication information and the transmitted data, so it is very secure to use SFTP. However, because this transfer method uses encryption/decryption technology, the transfer efficiency is much lower than normal FTP. If you require higher network security, you can use SFTP instead of FTP. HTTP & HTTPS HTTP is the basis for data communication. It defines the message format for communication between a Web browser and a Web server, and how the Web browser should respond to Web requests. HTTP uses TCP as the underlying transport and is a stateless protocol. This means that each command is executed independently and the receiver does not retain session information. Https is a secure version of HTTP in which communication is encrypted via TLS or SSL.

There are many kinds of enterprise documents, and the irregular operation of employees leads to the leakage of enterprise core documents from time to time. How to ensure the safety of document delivery? Raysync has released a new function in version 5.0.7.8 - high-speed file sharing download link binds to the first device, which makes administrator manage the file sharing conviencetly. 1. Function Introduction Check th option "Bind the first device when open the share link to download" in Raysync admin console. When this function is turned on, after the employee shares the file with the his partner through the "Share Download" link, only the first device is allowed to open and download, and this device will be recorded in the background. If you want to share it with multiple people, you need to notify the administrator and perform Unbind before the new device can reopen the link. For some enterprises with strict file security control, this function can well realize visual, controllable and traceable file outgoing, effectively control file outgoing and prevent data leakage. 2. Settings Step 1: Log in to the admin console. Step 2: Enter the admin console, check "Bind the first device when open the share link to download" in Settings-> General-> Common Settings. *The system is disabled by default and needs to be manually enabled by the administrator according to actual needs. 3. User Opeariong Interface The first device can open the downloadn link, view and download the file normally. If the other device try to open this link, the error prompt "This device is not authorized" will pop up. 4. Sharing Management The administrator can check the user who created the shared link, link share time, expired time, whether bind to the first device or not, and the device ID that binds as the first device. Besides, the administrator can also cancel and delete the file, unbind the link from the first device. After unbinding, you can reopen the link on a new device.

Today's data-driven world is demanding, requiring accuracy, speed, integrity, and most importantly safety. This is a daunting task. In the past, many organizations have relied heavily on the old version of the file transfer protocol to transfer files. But over time, FTP alternatives have become necessary because the security of this method has been tested by hackers. 4 Alternatives to File Transfer Protocols FTP alternatives include SFTP, HTTPS, AS2, and MFT. For example, in 2001, a serious breach occurred at Yale University, when more than 43,000 user IDs were exposed and all data was carefully collected from the FTP server. In the same year, Acer's customer details were stolen similarly. Moreover, credentials for 7,000 FTP sites have been distributed in underground forums, including the FTP server run by The New York Times. Security and file transfer are important issues for IT security professionals, but what is the best way to protect company data? Take advantage of more secure options. As many organizations gradually move beyond traditional FTP, they have chosen modern and secure FTP alternatives to transfer data, including: 1.SFTP_ SFTP is also known as FTP over SSH. It uses a secure channel between computer systems to prevent unauthorized disclosure during the transaction process, thereby reducing the risk in the data exchange process. The authentication of the SFTP connection involves user ID and password, SSH key, or both. It is also firewall-friendly and only needs to open a port number. 2.HTTPS Many sites tend to use HTTPS instead of traditional HTTP, but what are the main differences? First of all, traditional HTTP does not encrypt browser traffic, which brings security risks. In contrast, HTTPS uses Transport Layer Security to provide an additional layer of encryption. This will create a secure channel, so the integrity of the data will not be changed without your knowledge. HTTPS is very suitable for file transfer, where trading partners need a simple browser-based interface to upload data. 3.AS2 This is a popular method to safely and reliably transmit EDI data over the Internet. AS2 generates an "envelope" for data, allowing it to be sent using digital certificates and encryption. For example, Wal-Mart is widely known for its use of EDI through AS2 and has played an important role in driving adoption in the retail industry. 4.MFT The way to support the above options and make FTP more secure is Managed File Transfer . This security option simplifies the data exchange between the system, employees, and customers. It supports multiple protocols and encryption standards, and MFT provides a wide range of security functions that can meet strict security policies to comply with PCI DSS, HIPAA, GLBA, and other regulatory requirements. The MFT solution provides advanced authentication and data encryption to provide safe and reliable file transfer. You can also track user visits and transfer activities through the reporting function. More importantly, managed file transfer can solve other problems or troubles you may encounter, including the need for automatic file encryption, workflow and project automation, file transfer monitoring and notification, and easy file sharing with third-party suppliers and trading partners. In general, managed file transfer provides the best choice. It is a secure FTP alternative to quickly and effectively manage data transfers through detailed audit records. It is preventive, not reactive, which is most needed by security experts in today's environment. It is supported on many platforms , cloud , and hybrid environments), so you can safely transfer files anytime, anywhere.

The file transfer protocolserver runs a program that utilizes the file transfer protocol and allows you to upload and download files. By default, the file transfer protocol is not secure because the data it transmits is not encrypted. All file transfer protocol servers on this list include options for encrypting and protecting data by using secure protocols such as SFTP or FTP/FTPS. File transfer protocol servers are usually used to allow remote workers to upload or download files from the server. Network and system administrators also use it to back up network configuration and run updates. There are many file transfer protocol server programs available, from free software with basic functions to commercial products with advanced functions such as mobile device access. In this article, I will share the best file transfer protocol server for Windows. 1. FileZilla Server FileZilla is an open-source FTP server for Windows. It supports FTP and FTP over TLS, the latter can provide encryption between the server and the client. FileZilla server has a simple and easy-to-use interface. It provides the basic functions expected in an FTP server, such as creating user accounts, speed limits, logging, IP filtering, groups, and fine-grained permissions. For basic FTP tasks , this is a good choice. It lacks corporate functions, so I will be cautious when providing it to the outside world. It uses FTP by default, so it is not secure and you will need to enable FTP over TLS to encrypt traffic. The setup is easy, just run the installer, select a management port and start the server interface. Then, you only need to create a user or group with permissions to the home directory to start using it. 2.SolarWinds SFTP/SCP Server SolarWinds SFTP/SCP server is designed for network and system administrators. It is an ideal FTP server for backing up configuration files, downloading images, and transferring large files. By default, it is secure and uses TCP port 22 to safely transmit data over an insecure connection. I use it to back up the configuration on Cisco routers and switches. Installation is very simple, with minimal configuration , and you are ready to go. It can be set to run as a service, so it is always available. 3.Serv-U Serv-U is designed for small businesses that need to transfer files quickly, easily, and securely. Serv-U supports FTP and FTPS for secure file transfer. You can use SSL or TLS to encrypt communications to protect data during transfer. One of my favorite features of this product is the ability to transfer files from a web browser or mobile device. This eliminates the need for users to set up an FTP client to download or upload files. The web and mobile interface makes it easy for you to view, upload and download files. Using interactive drag and drop options, your users can share files from anywhere.

File Transfer Protocol is a widely used network protocol for transferring files between computers over a TCP/IP-based network . FTP allows people and applications to exchange and share data in their offices and over the Internet. FTP was one of the first technologies developed to address this common need, and after several generations of enhancements, it is still the second most popular protocol in use today . FTP Application FTP is used in many daily business operations, including business-to-business and peer-to-peer data transfer use cases: Organizations use FTP to allow employees to share files across different locations and branches. Employees use FTP to securely share files with colleagues and external business partners; Employees use FTP to securely share files with colleagues and external business partners; IT teams use FTP to transfer data back to the disaster recovery site; Webmaster teams use FTP Transfer web pages, web application files, and images to their web server. How to Transfer Files via FTP? The file transfer protocol works in a client-server model, where the FTP server and FTP client perform file transfer operations. Configure an FTP server in the network and determine a specific file storage location to become shared storage, which will host the files you want to share. End users will access this file server via FTP to start copying files to their local folder/system. FTP requires a TCP/IP network to run, and it relies on the use of one or more FTP clients. The FTP client acts as a communication agent to interact with the server and download or upload files. In other words, the FTP client sends a connection to the FTP server. After the FTP server monitors the client's request for uploading or downloading a file, it executes the file transfer operation. What is the Use of An FTP Client? Decades ago, FTP clients were just command-line interface applications. They now provide an easy-to-use, intuitive interface to facilitate and simplify file transfers. FTP clients are used on desktops, servers, and mobile devices, and they can be used as simple extensions to stand-alone applications, web clients, and web browsers. Active and Passive FTP Server Connection The FTP server can support active and passive connections with FTP clients. In an active FTP connection, the client opens a port and listens when the server actively connects to it. In a passive connection, the server opens a port and passively listens, which allows the client to connect to it. Conclusion FTP has been around for more than four years, and it has witnessed major changes in encryption standards and file transfer capabilities. This chart records the evolution of FTP and the introduction of hosted file transfers. It provides support for secure protocols and advanced management functions for secure and controlled file transfers. The Raysync high-speed transfer protocol is a core technology by Raysync based on the UDP protocol, which can overcome the limitations of traditional networks and hardware, the bandwidth utilization rate is more than 96%, and the transmission speed is 100 times faster than FTP. It can easily meet the safe, fast, and stable transmission requirements of TB-level large files and massive small files.

File transfer could be a key part of an associate organization's business, answerable for all sorts of sensitive data. As a lot of and a lot of processes area unit digitized, the number of knowledge changed is additionally increasing. The file transfer protocol is that the key to protecting the knowledge between the end and also the network. However, organizations consider numerous agreements, counting on the sort of knowledge and destination—internal and external transmissions typically have different needs, and knowledge rules could vary from country to country. Different file sharing solutions area units are typically accustomed handle differing kinds of file transfers. However, this may cause server sprawl and increase the quality of the file transfer surroundings, creating management troublesome and long. additionally, vulnerabilities in practicality area units are usually blocked by rigid and fallible custom scripts. this is often particularly common for organizations that consider previous protocols and file transfer strategies. With the event of the surroundings and also the development of security needs, a far better thanks to managing file sharing is required. Before delving into best practices and secure file transfer services, let's take a glance at the various varieties of protocols used for secure file transfer. Top protocol for secure file transfer The original file transfer protocol established an easy technique of transferring files over the network. however, FTP was designed within the Seventies, long before knowledge security became a very important issue. FTP still exists, however with the introduction of secure file transfer protocols, its use has been greatly reduced. So what's a secure file transfer protocol? the general public can answer SFTP, that is the solution. Though FTP is termed associate insecure protocol as a result of it doesn't offer secret writing, it will offer a secure file transfer protocol. SSH File Transfer Protocol SFTP could be a protocol developed by the web Engineering Task Force and is perhaps the foremost common file transfer protocol in use nowadays. SFTP relies on the Secure Shell secret writing technology and is employed to encode the transmitted knowledge. This secret writing half is completed by sending data in knowledge packets rather than plain text, which typically leads to quicker transmission times compared to FTP. SFTP supports the employment of key pairs and host-based authentication, permitting SFTP to be used for sensitive knowledge, like personal data. SSL-based file transfer protocol FTPS attempts to use Secure Sockets Layer to create FTP security. However, SSL was deprecated in 2015, thus although most FTPS servers use Transport Layer Security , we tend to still decision it FTPS. TLS uses certificates to certify users and forestall data from being accessed by unauthorized parties. FTPS needs 2 ports on the client-server, which may build FTPS transmission through the firewall harder. there's conjointly express FTPS , that provides further options for secure file sharing. Applicability Statement two The AS2 protocol is employed by a large variety of retail and automotive trade mercantilism partners. AS2 sends encrypted messages supported by S/MIME and HTTPS. AS2 conjointly supports digital signatures and Message Disposition Notification , which offer senders plain receipts. ODETTE File Transfer Protocol two OFTP2 could be a TCP/IP protocol, that is extremely widespread among automobile firms, particularly European automobile firms. OFTP2 is extremely just like AS2 and supports non-repudiation through receipts. significantly, OFTP2 will compress giant amounts of information, creating OFTP2 and efficient means that of transferring giant files. the first OFTP was introduced in 1986 by the EU Teletransmission knowledge Exchange Organization . In addition, OFTP2 will operate in a very push and pull mode via an added network . User Datagram Protocol UDP could be a transport layer protocol just like a communications protocol. However, UDP doesn't embody several of the "overheads" inexplicit by alternative protocols, like handshakes, certificates, or receipts. This makes UDP a quicker technique of causing knowledge like video or audio files, particularly once sending over long-distance networks that have high latency. However, this speed has obvious disadvantages, together with packet loss. Best Practices for Secure File Transfer——Raysync File transfer needs are numerous and evolving, counting on the organization's business. New protocols area unit invariably below development, and knowledge rules generally appear to be fully unfixed. Raysync is based on the needs of customers in the film media, IT Internet, and other industries. Raysync uses AES-256 encryption technology between the client and the server to ensure end-to-end data security. For port issues, Raysync only needs to expose one port to meet the access needs of all users, greatly reducing the risk of firewall port exposure; Hash verification protection is performed at the transmission message level, file block, and entire file to ensure the integrity of the transmission content sex.

When companies are transferring files over long distances, when they choose traditional FTP, network disks, etc. to transfer large files, in addition to slow speed, they often encounter transmission errors, transmission interruptions, and resuming transmissions. Although the traditional FTP transfer method supports the batch transfer of folders, when the number of files is large, in addition to the very slow speed, there are often problems such as missing files, file content errors, and inconsistent file numbers. When the file capacity increases and the network environment becomes worse, the efficiency of file transfer and data exchange is low, and the security is poor. If the file is larger, usually a lower method such as express hard disk is used, which cannot meet the requirements of enterprises to obtain files on time. Seriously affect the overall operating efficiency of the enterprise. This type of data transfer requires the use of data transfer protocols to ensure efficient and rapid transfer on high-speed networks. Several new data transfer protocols based on TCP or UDP have been introduced, and some comparative analysis and research have been carried out on such protocols. There are currently several data transfer protocols and congestion control mechanisms GridFTP, FASP, QUIC, BBR, and LEDBAT, which are potential candidates for comparison in various scenarios. These protocols are designed to make fair use of available bandwidth among competing streams and provide reduced packet loss, reduced delay, and fast data transmission. In this paper, the behavior and performance of the data transfer protocol in various scenarios are explained. These scenarios include transfers with various file sizes, multiple streams, background, and competing for traffic. The results show that FASP and GridFTP have the best performance among all protocols in most scenarios, especially for long-distance transfer with a large bandwidth-delay product . Due to the nature of its current implementation, QUIC has the lowest performance, which limits the size of the transmitted data and the bandwidth used. TCP BBR performs well in short-distance scenarios, but its performance decreases as the distance increases. The performance of LEDBAT cannot be predicted, so a complete evaluation cannot be performed. Comparing the performance of the protocol with background traffic and competing traffic shows that, except for FASP, most protocols are fair and radical. In addition, QUIC and FASP, which have the highest CPU utilization, are used to measure the resource utilization of each protocol on the sender and receiver. The performance of LEDBAT cannot be predicted, so a complete evaluation cannot be performed.
